Is it possible to connect an RFID reader/writer module directly to a M
I'm a hobbyist, just starting out.
I would like to be able to work with an RFID reader/writer module like this one: http://www.kynix.com/Product/Cate/747.ht....
All of the solutions I have seen online for doing this so far involve connecting the RFID reader/writer module to an Arduino or Raspberry Pi and then connecting one of those to a larger computer (like a MacBook).
Why are they doing this? Why use a Raspberry Pi at all for something like this when you have a MacBook at your disposal? Is it because the RFID reader/writer uses SPI connections? If so, why not just use a SPI-USB bridge/converter between the RFID reader/writer module and the MacBook?
I'm obviously missing something and I know it. I'm new to this stuff. I'm not trying to be critical - I'm just asking questions.
Is this a good question?
